fix(sdk): change insomnia.test mechanism to improve the nested test cases

[ihexxa]

Changes

• Change the mechanism of insomnia.test to improve the nested test cases
• Support await insomnia.test
• Enable autocomplete for insomnia.test and insomnia.expect
• Added smoke tests

Add sync or async cases in script to test it:

          insomnia.test('asyncHappyTestInFunc', () => {
            insomnia.expect(200).to.eql(200);
          });

          insomnia.test('asyncHappyTestInFunc', async () => {
            insomnia.expect(200).to.eql(200);
          });

Could there be any compatibility issues since the function passed to test() is executed asynchronously now?

@yaoweiprc This is a good question, theoretically, for those who pass function without async, as those tests are still executed synchronously, so the behavior should not change. for those who pass function with async, originally their code returned an error and didn't work, then the currently patch should work.

Nit: Why don't we expose insomnia.test insomnia.expect method in snippets?
I see there's logic making test/expect as private property and do not expose them in getRequestScriptSnippets method while postman has hints for pm.test pm.exepct.

@cwangsmv Good catch, it just tries to wrap _expect and _test so that we can add some manual validation, let me tinker it a bit to see if I can expose them.
